Because he is the President of the most powerful nation on earth. Slate him to his face in private by all means, but just riling him for the sake of it is just risking him upping the anti, be it a trade war, withdrawal of support from NATO, whatever. It is not in the UK's interest to be an enemy of the US.

Do drop the whataboutery. Those planning to protest should use their imagination to do something better than allowing their displeasure to be hijacked by serial anarchists, which is exactly what will happen.

OP: What do we think of the Trump blimp?

Response: Shouldn't be allowed.

Me; Rubbish. They have the right to this chosen form of peaceful protest.

You: But OTHER people will also protest and cause disorder.

You're accusing ME of 'whataboutery'? Haha.

The above post is simply my opinion. I am not bullying you, should it differ from your own.

'They' have a right to peaceful protest (but it won't be will it?), the mayor of London should know better than to approve a public insult.

The police might yet stop it. Or the air traffic folk. But I cannot see how Khan had any (moral, at least) right to prevent it. What if 50,000 marchers each held up a 3ft cardboard cut-out of the same TrumpBaby image? Would you expect Khan, or some other form of authority, to put a stop to that as well? Slippery slope, the type of political censorship you are advocating.
